We've mentioned this tech from Seagate before, MACH.2 Multi-Actuator technology, basically two magnetic heads and a bit of technology that sounds familiar to raid. Seagate demonstrated up to 480MB/s sustained throughput - the fastest ever from a single hard drive, and 60 percent faster than a 15K drive.

Today Seagate said its new MACH.2™ Multi Actuator technology has enabled them to set a new hard drive speed record, demonstrating up to 480MB/s sustained throughput — the fastest ever. Seagate formally introduced its MACH.2 Multi Actuator technology yesterday, which has now been deployed in development units for customer testing prior to productization. Seagate’s advanced engineering team also announced a breakthrough in the demonstrated reliability of its HAMR (Heat-Assisted Magnetic Recording) technology hard drives. Seagate revealed that its HAMR read/write heads have achieved unprecedented results in long-term reliability tests that surpass customer requirements by a factor of 20.
